Notes :
1. Availability of the shaded IRQs depends on the setting in the BIOS. According to the PCI Standard,
PCI Interrupts IRQA-IRQD can be shared.
2. These interrupt lines are managed by the PnP handler and are subject to change during system
initialisation.
3. IRQ16 to IRQ26 are APIC interrupts
